The CNEP, bridge between research and industries.

We assist companies, research organizations and innovation centers in their development, sustainability or analysis of polymeric materials

Skills, offers and services

Since 1986, the CNEP has supported you in understanding the aging phenomena of your polymer materials. Thanks to our expertise and knowledge in chemistry we can guide you to effectively control the durability or degradation of your products.

In addition, our skills in analysis of plastic materials and our many scientific devices allow us to respond to your requests for characterization or expertise of failures.

Established in the Auvergne-Rhône-Alpes region near Clermont-Ferrand (France) over more than 1500m², our laboratory has one of the largest parks of accelerated photo-aging chambers, ventilated and climatic ovens as well as more specific durability or aging prediction devices.

The CNEP also has a wide range of physico-chemical analysis devices, including multiple spectrometers, microscopes, chromatographies or characterization devices.

This equipment, covering a vast experimental and analytical field, allows us to respond quickly and efficiently to the numerous requests concerning polymer materials.

Information on materials with "acquired biodegradability" more conveniently called "oxo-biodegradable" is generally not offered in an acceptable form and these materials have gradually acquired a bad reputation, sometimes justified by errors in the development of these materials.

La certification ISO 9001 - 2015

L'ISO 9001:2015 spécifie les exigences relatives au système de management de la qualité lorsqu'un organisme:

a) doit démontrer son aptitude à fournir constamment des produits et des services conformes aux exigences des clients et aux exigences légales et réglementaires applicables, et

b) vise à accroître la satisfaction de ses clients par l'application efficace du système, y compris les processus pour l'amélioration du système et l'assurance de la conformité aux exigences des clients et aux exigences légales et réglementaires applicables.

Toutes les exigences de l'ISO 9001:2015 sont génériques et prévues pour s'appliquer à tout organisme, quels que soient son type ou sa taille, ou les produits et services qu'il fournit.

Obtenir la certification ISO 9001:2015, c’est s’appuyer sur 8 principes de management :
• l’orientation client ;
• l’implication du personnel ;
• l’approche processus ;
• l’amélioration continue ;
• la gestion par approche système ;
• le leadership ;
• la prise de décision fondée sur des preuves ;
• le management des relations avec les parties intéressées.
